1'0 a-ZZ whom it may concern..-

Be it known that I, OSWALD JACKSON, of Carrollton, in the county ofGreene and State of Illinois, have invented certain new and usefulImprovements in \Vire-Fence Machines, of which the following is a full,clear, and exact description.

This invention has relation toiinprovements in a machine formanufacturing that class of fencing in which the pickets or slats areconnected by wire runners composed of two strands twisted at suitableintervals around each picket; and the invention consists in theconstruction and arrangement of parts, as wll be hereinafter describednd particularly pointed out in the claims.

in the accompanying drawings, Figure l is a top plan view of my improvedmachine. Fig. 2 is a longitudinal section thereof. Fig. 3 is a sectionthrough line as as, Fig. 1.v Fig. 4 is a section through the line y 3Fig. 1. Fig. 5 is an enlarged detail of one of the spoolclamps and itscontiguous part-s. Fig. 6 is an enlarged detail view of one of thetwisters. Fig. 7 is a detail of one of the spools, showing the means forlooking it to its shaft.

The letter A denotes the frame-work of the machine, within which theparts shown have support.

Upon a shaft, B, journaled in the sides of the frame are mounted anydesired numberof spools 0, according to the number of wire stripsemployed in the manufacture of the fencing, each of said spoolscontaining wire which is fed therefrom to the twisting devices.

These spools are arranged side by side on the shaft, the ends of twowires from two of the spools passing through eyes 6, secured to across-piece of the frame. Upon a beam, M, as shown in Fig. 4, arrangedbeneath and par aflel with tl1espool-shaft,a1'e secured the rods of thetension devices 13, each rod having at its upper end a clamp, m, whichis secured between each set of spools by means of screwthreaded bolts n.

It will readily be seen that when the spools are to be replenished withwire the tension devices are relaxed by unscrewing the bolts therefrom.

The bodies of the spools are provided with perforations, whichcommunicate with perforations in the shaft, in which are inserted pinsZ. These pins and the construction of the spools and the shaft allow theoperator to throw one or more sets of the spools in or out of operativeconnection with the shaft at will.

The wires \V pass from the spools to the twisting devices. Theseconsisteachofahollow shaft, N, having a pinion, P, rigidly mounted thereon.Upon the forward end of each shaft N is formed a wire-spreader,consisting of a fork, P, having eyes 6, which carry the wire,

and provided upon its end with a ring, B, through which the ends of thewire pass. This ring not only serves to strengthen the fork P, but itforms a solid support for the pickets which rest against it as thetwisting shaft is operated. These several shafts are mounted in a frame,0, in front of the spools.

Supported in suitable bearings, S, upon the frame 0 is a raclebar, R,arranged above and meshing with the pinions P upon the twisting-shafts.This rack-baris also provided on its upper surface with asecond rack, Pwhich extends from the central portion of the bar to the end thereof,and which engages a pinion or gear wheel, I, mounted on a post, 0, andoperated by a crank, t, by means of which the rack-bar is given motionto twist the wire to the pickets.

The operation of my invention is as follows: \Vhen the wire is fed fromthe spools to the twisting devices, the pinion wheel being operated bythe crank, said wheel operating the rack-bar in connection with thepinions of the shafts N, the rack-bar causes the twisters to revolve andtwist the wire to the picket which abuts against the rings R. Therackbar is then run back, which causes the picket to travel away fromthe ring, whereby another piclrct is substituted against the ring, andthe same operation above described is repeated.

By my invention I am able to greatly simplify the mechanism in thisclass of machines. Moreover, by affording the pickets support upon theend of the twisting device, the wires are fastened more securely, beingtwisted more closely upon the picket.

By connecting the tension devices to the spools all wear of the wire isavoided, the danger of breaking is in great measure decreased, and theadjustment is more exact and more easily effected.

Having now described my invention, what .I claim, and desire to secureby Letters Patent,

1. The combination, with the perforated shaft B, having the tensiondevices L at suitable intervals thereon, the perforated spools Oon saidshaft, provided with wires \V,and the pins l, engaging the perforationsof the spools and shaft, whereby one or more spools are thrown intoengagement with the shaft, of the hollow shafts N, having the pinions1?, forks P, having eyes 6 and rings R, and means, as described, foroperating the above parts, as and for the purpose set forth.

2. The combination, with the perforated shaft B, having perforatedspools mounted thereon provided with wires, said spools keyed to saidshaft by means of pins 1, engaging the perforations of the spools andshaft, of the hollow shafts N, having the pinions P, forks 1?, providedwith eyes 6 and ring R, whereby the wires from the spools are conveyedthrough the eyes e, shafts N, 25

and eyes 6, and twisted to the picket which abuts against the rings R,and the double rack-bar R P engaging the pinions P, and a gear-wheel foroperating the shafts N and their devices, as shown and described.

3. The combination, with the shaft B, having the wired spools 0, eachspool adapted to be keyed to the shaft by means of pins'l, engagingperforations in the spools and shaft, the hollow shafts N, havingpinions Rand forks 1?, having eyes 6 and ring R, of the double rack-barR P, sliding in the bearings S on the frame 0, to allow the pinions ofthe shafts N to engage the under side of the rack-bar operated by thegear-wheel I, which meshes with the upper rack to twist the wires to thepicket, as shown and described.

In testimony whereof I have hereunto set my hand this 30th day ofOctober, 1884.
